Depends on your chip stack, for instance if you are down to below 10 BBs I would definitely shove all-in pre flop with practically any pocket pair, after all you are holding a pair which beats any suited connectors, unless of course they make a straight or flush, and you are in a situation where you need to double up.
The all-in shoves I hate are
hands like A/K or A/Q etc, sure you have a top card with a decent kicker but you do have to connect in order to win the hand, even against Pocket Deuces, It all boils down to your own personal choice, and you cannot wait around for Pocket Rocket's to make an appearance.
Everyone has a favorite hand and when in a situation where they need to double up, will push all-in with it, because they believe it is a lucky hand, that always wins for them, but as we all know there are no sure winning hand's, it is all superstition, and they will remember when it hits for them but forget the times it misses.
Once in a Tournament I was dealt K/J off suit on the BB, not my favorite hand but is a good starting hand, the player UTG pushed all-in with J/10 and declared it to the whole table, saying it was his favorite hand, I waited to see what the rest of the table were going to do, and when everyone folded to me I called simply because I only had to miss the 10, I had actually considered folding if someone else had re-raised before me, but when we both missed the Flop, Turn and River, my King high won! and that is why I do not have a favorite hand.
When the fun Stops, STOP!
